Lette/rs Patent No. 98,477 dated January 4,1870.

IMPROVED ASH-SIFTER, LACH, AND SMOKE-HOUSE.

The Schedule referred to in these Letters` Patent and' making part of the same.

I, DAVID WILLsoN-DOAN, of the city of Rochester, in the county of Monroe, and State of New York, have invented certain Improvements-in Combined Ash-Safe, Sifter, Leach, and Smoke-House, of which the following is a specification.

My invention relates to the construction of' an apparatus which will answer'the several purposes of an ash-safe, sifter, leach, and smoke-house; and consists in the construction and arrangement of a metallic ash-receptaclevand sifter, the-former provided with an inclined perforated bottom, which receives the ashes discharged from the sifter, arranged at the top, said vessel being supported by pivots in a `suitable frame, and secured in a Vertical position by a locking-pin or equivalent device, whichl enables it to be readily swung over for the purpose ofem-ptying the 'same of its contents.

lIn .the drawings- Figure l is a sectional elevation of my apparatus.

Figure II is a front elevation of same.

Figure III is a plan view of cover removed, showing the ash-sifter.

Figure IV is a plan view,showing the rods arranged crosswise, near the top of the safe.

Like 'letters designate like parts in each of the tigures.

Ais the ash-safe, constructed of fire-proof material, with the bottom thereof inclined, and provided with peribrations, al, and the top closed by a hinged cover, a?.

Pivot-pins p are attached tothe safe, a little above the centre of gravity thereof, and resting in suitable bearings on the posts b1 of the"framework. The. latter consists of the two upright posts b1, supporting the ash-safe, and a bottom cross-piece, b2, connecting said posts.

The location of the pivots p causes the safe A to hang in a vertical position between the posts b1, when it is secured in such position by means of a pin, s, passing through one ofthe posts b1, and locking in the side of the safe, or by any other equivalent device.

' Upon releasing said pin or locking-device, the safe A ma be readily swung over on its pivots, and emptied of its contents. v

C is the ash-sifter, arrangedin and near the top of the ash-safe A. The sifting-surface of the same consists of metallic rods or wires, r, arranged cyl ndrically around and parallel to the shaft c of the sifter, said rods or wires being attached to circular metallic disks or heads, c1, mounted on theshaft c.

A door or gate, d, is provided iu the sifter G,- for the purpose of filling in the material to be sifted, and removing therefrom the remaining cinders, after the operation of sifting has been performed.

This door is constructed of the same kind of metallic rods or wires, which are used for the sifter proper,

said rods or wires heilig attached to two' rrietallic segments, e e, hung ou the sitter-rod f, and rest, when the door is closed, ou the rod g. Consequently, the Wires of the door d form part of the sitting-surface when the door is closed. A

A pin, h, which passes through an opening formed by bending the rod g, and bears on, the adjacent wires of the gate and of the sitter proper, serves to lock'the door d when required'. The door isshown open in 'dotted liuesin Fig. I. i' i The sitter-shaft c is supported in the sides o'f the ash-safeA, and carries a hand-crank, t', ori the .end projecting through the side of the safe. made detachable, either by cutting out the .sides of the safe, or by arranging the shaft c so that it may be drawn out.

When the safe is to be used as a smoke-house, the

ash-sitter C is removed, and two rods or bars, m m,'

are inserted crosswise, near the top of the sate, holes being provided therein for the reception of these rods, on which the meat or fish, to be smoked, is suspended. The arrangement ofthese rods is clearly shown inv Fig. IV. r

The operation of my apparatus is as follows:

The ash-sifter is filled with the ashes and cinders, and, by a few turns of the same, the ashes are separated from the cinders, andfall' to the bottom of the safe, while the cinders remain in the sitter, .whence they are removed.

If used as a leach, the water is poured in at the top l of the safe, and the lye passes oi through the perforations in the hottomrin the ordinary manner. The remaining ashes are discharged from the safe by turning the same ou its pivots.

If used as a smoke-house, thesifter is removed, as

above stated, and the cross-bars are inserted, the perforations in the bottom forming draught-openings in this case. v

It is evident, from the above description, that my apparatus combines the advantages of beingportable, lire-proof, and easily handled, at the same time answering,the several purposes ofan ash-safe, sifter, leach,

and smoke-house, to all of which itis adapt-ed, as be- I fore described. v

I am aware that a rotary ash-sifter, arranged in an ash-.box,'is old, and such, broadly, I do not claim; but

What I claim as my invention,-is' The pi voted metallic Iash-safe A, provided with an inclined perforated bottom, al., combined and arranged with the rotary sifter C, substantially as and for the purposeshereinbefore set forth.
